Why it works: Onion and pepper are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 68,474 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Beefsteak Smothered with Onions
Ingredients
Directions
Heat lard in a skillet over medium heat.
Peel and slice the onions, then layer them over the steak until the skillet is full.
Season with pepper and coarse sea salt, cover tightly, and cook.
Once the onion juice has evaporated and the meat starts to fry, remove the onions.
Turn the steak to brown the other side, then replace the onions carefully to avoid burning.

What each ingredient does
- Onions
- Release moisture that steams the steak, then add sweetness and flavour as they cook down.
- Lard
- Conducts heat and fries the steak surface, adding richness and browning.
- Steak
- Main protein that browns in the fat and sets the core of the dish.
The step that matters
Removing the onions after the juice evaporates. Onions left in the pan too long can scorch and turn bitter before the steak browns. Once their juice has cooked off, the meat can fry directly, so removing them at that point protects both flavour and colour.
